TECHNICAL FAQsHere are answers to the most common technical problems users encounter during a webcast: Q: Why can’t I hear the audio part of the webcast?
A: Try increasing the volume on your computer.
Q: I just entered the webcast and do not see the slide that the speaker is referring to. What should I do?A: The slides are constantly being pushed to your screen. You should refresh (hit F5) to view the latest slide.

Overview
Tools for tuning Five tuning methods Takin’ Out the Trash Tuning disk subsystems Tuning memory subsystems Tuning CPUs Tuning NICs
Tuning Tools
Performance Logs and Alerts (perfmon) – but don’t worry, you needn’t look at every single thing that Perfmon offers!
Task Manager logman – command-line perfmon logger Another excellent tool: Network Monitor (Netmon) Some nifty free Sysinternals tools: pagedfrg, contig,
Process Explorer Msconfig
Meet Perfmonthe Performance Monitor
You’ve probably looked at it before Things are grouped into “objects” and objects
are divided into “counters” Example: things related to the CPUs are in
an object called “processor” Lets you either log info long-term or view in
real time
Perfmon Tips
Use Perfmon on one computer to log another computer
Alerts can be useful, even if they’re simple The key to using Perfmon is in finding a
small number of things to log, and looking at them periodically

Tuning Basics
The object of tuning is to find the bottleneck Bottlenecks are where the computer spends most
of its time, the binding constraint File servers bottleneck in different places than
applications servers File servers bottleneck on the network card
interface and the disk interface App servers bottleneck on memory and CPU power
Five Tuning Solutions
1. Delete useless junk (programs that waste resources, unnecessary services)
2. Buy faster hardware
3. Reconfigure the hardware for better throughput (i.e., registry tweaks)
4. Clean resources
5. Move loads (apps) to other systems
Eliminating Junk
Fire up Task Manager and ask: What is all that stuff?
MSconfig32 can help So can Process Explorer and Autoruns from
www.sysinternals.com Then go after the services

Killing Unnecessary Services
Workstation services:– Server/computer browser– Any Web/FTP server– Wireless Zero Configuration (unless 802.1x)– WebClient (unless you know you need it)– Infrared Monitor… and tons others; look your
system over and experiment Tune your personal firewall/antivirus software
Disk TuningDisk Tuningcounters and solutionscounters and solutions
Disk TuningDisk Tuningcounters and solutionscounters and solutions
Must use diskperf –y on W2k and reboot… but it’s no longer necessary on XP/.NET
You want to see:– Physical Disk / Percent disk time < 90– Physical Disk / queue length <= 2
Solutions: faster interfaces (UDMA-133) faster host adapters (SCSI), bus mastering (if it doesn’t already exist), move processes
Disk Tuning
If using two EIDE drives, put them on different channels
Use NTFS… not FAT32 Defrag volumes periodically Sysinternal’s “contig” will make a particular
file contiguous On an AD DC, defrag Active Directory with
NTDSUTIL
Network TuningNetwork Tuningwhat to watchwhat to watch
Network TuningNetwork Tuningwhat to watchwhat to watch
Network Interface/Output Queue Length <= 2 Look for increases in Server object, counter
– Blocking requests rejected– Errors system– Pool non-paged failures, pool paged failures– Sessions errored out
Rearrange binding order or provider order if you have multiple protocols
Kill unnecessary protocols
Memory Tuningpagefile optimization
Defrag pagefile with Sysinternals’ free pagedfrg.exe
You no longer need a pagefile >= RAM if you choose minidumps or kernel memory dumps
Spread pagefile over several physical drives This, of course, only makes sense if those
drives run asynchronously
Memory Tuningsizing pagefiles: general info
You cannot have too large of a pagefile – you don’t slow down your system; although, of course, you may burn too much disk space
Set maximum pagefile size = minimum And provide space for crashdumps
Click the “Ask a question” button in the lower left section of your screen to submit a question.
Memory Tuningsizing pagefiles: specifics
Size with XP’s Task Manager / Performance / Commit Charge (K) / Peak or log Perfmon’s Memory/Committed Bytes counter, take peak
Note that they may not match, as Perfmon and Taskman poll at different intervals
This will almost always be more than you’ll ever need – look at Paging File / % Usage Peak
Tuning CPUsperfmon counters
Processor counters; want to see:– percent CPU time < 80 percent– System/Processor Queue Length <= 2 on UP
system Run the histogram to find out who are the
hogs
And for heaven’s sake don’t run the silly 3D screensavers!
